Loc Tan Le Tran Nhan Tong Institute, Vietnam National University, Hanoi, Vietnam ABSTRACT Although Buddhist education has been widely used all over the world, Vietnamese students cannot currently access it at school. Recently, some Truc Lam (Bamboo Forest) Zen monasteries have offered religious education to adolescents in the hope of improving their moral behavior. However, no empirical studies have evaluated the effectiveness of these efforts. As a result, this study examined whether Buddhism helps teenagers develop moral behaviors. The findings showed that Buddhist religious education can enhance adolescents’ understanding of Buddhist doctrines, increase their faith, and promote Buddhist practices. As a result, they committed antisocial behaviors less often. KEYWORDS Buddhism; Buddhist education; religious education; adolescence; moral development Introduction The primary goal of Buddhist education is to help learners achieve wisdom (Meshram 2013). According to Kung (1997, 5), people engage in negative actions because of their lack of wisdom. Sivasai (2014, 69) claimed that religious education could help to reduce ignorance, the root cause of suffering. Buddhist religious education has existed since the time of Shakyamuni Buddha, who was stated by Mahathera (1998, 31) and Paramananda (2014, 17) to be the greatest moral teacher. He not only taught his disciples (monks and nuns) how to become enlightened, but also taught lay followers to live morally. For example, the Buddha taught a layman named Anathapindika and 500 other lay followers to abide by the Five Precepts (no killing, no stealing, no sexual misconduct, no lying, and no intoxicants) to avoid unwholesome karma (S. Thich 2019, 1119–1125). As Aguirre (2017, 1304) noted, virtues are needed for global development. Hence, Kandahjaya (2014, 25–26) argued that Buddhism could contribute to that. Furthermore, it also ensures sustainable development because of its ability to provide people with the knowledge, skills, attitudes, and values necessary to shape a sustainable future (Sivasai 2014, 75). Although Buddhism is not native to Vietnam, the religion has been closely integrated into traditional Vietnamese culture for approximately 2000 years (L. Nguyen 2012, 15). Historically, it played a significant role in the national education system (H. Nguyen and C. Nguyen 2016). Under the Tran Dynasty, Tran Thai Tong and Tran Nhan Tong (kings who were also Zen Masters) offered the people Buddhist education to enhance ß 2021 The Religious Education Association 2 L. T. LE their morality. King Tran Thai Tong (b. 1218–d. 1277), who led the people to defeat the Mongols invading Dai Viet (the name of Vietnam from the 11th to 19th centuries) for the first time, wrote a discourse to teach his people how to practice the Five Precepts (T. Tran 2017, 47–52). King Tran Nhan Tong (b.1258–d.1308), after leading resistance forces to defeat the Mongol invaders twice, abdicated his throne to live as an ascetic. He then founded the Truc Lam (Bamboo Forest) Zen sect and traveled around the country to teach his people the Ten Good Deeds (T. Thich 1995, 34). However, Buddhism is now not taught in Vietnamese state schools. H. Nguyen and C. Nguyen (2016) explained that religious education is not part of the school curriculum because the promulgation of religion is forbidden in state schools under Vietnam’s Law on Education. This article explores the significance of this. At a conference on Buddhist education held by the Vietnam Buddhist Institute in 2019 in Ho Chi Minh City, several scholars suggested that certain Buddhist doctrines could help young improve their attitudes and behavior. Tran and Nguyen (2019) proposed teaching the Law of Cause and Effect to teenagers because it could prevent them from engaging in antisocial behaviors. H. D. Le (2019) stated that the Five Precepts and the Six Rules of Harmony could encourage teenagers to live harmoniously with others in the community. In addition, L. T. Nguyen (2019) and H. T. Le (2019) argued that the Five Precepts and the Four Debts of Gratitude may help adolescents control antisocial behaviors. What they suggested may help, but is unconvincing because of a lack of empirical evidence. They merely analyzed the relevant Buddhist doctrines and came to a theoretical conclusion. Empirical research is needed to provide more persuasive evidence. This work examines whether Buddhist education can help teenagers control antisocial behaviors.1 The research outcome may help the development of Buddhist education, not only in Vietnam but also worldwide. A theory of Buddhist education According to Oh and Park (1988), Buddhist education should help learners enhance their morality by combining religious faith, understanding, and practice, of which the first is the most important.2 To achieve the goal, teachers, as Oh and Park (1988, 253) stated, must be responsible for providing a good education. To define what a good education is, Groome (1980, 20–21) investigated definitions provided by Lawrence Cremin, Alfred North Whitehead, and Greek pedagogs; he concluded that it “must be cognitive, affective, and behavioral.” The term “cognitive” in Groome’s observation is equivalent to the concept of intellectuality in Buddhism; “affective” is similar to emotions; and “behavioral” relates closely to Buddhist ethical morality (Oh and Park 1988, 252). As a result, they claimed that their model was in line with Groome’s conclusions. Furthermore, they suggested that Buddhist education should be held in temples for 1 In a Vietnamese context, antisocial behaviors are understood to be individual actions which are harmful to society and the national tradition. The terms saddha (Pali) and sraddha (Sanskrit) are often translated “faith” in English. These terms imply confidence in the Buddha’s teachings (or the recitation of sacred texts and mantras directed at the Buddha or celestial Buddhas/ Bodhisattvas) to bring about their concomitant results, i.e., nirvana, or a more worldly effect of some kind. My thanks to Dr. Chris Gibbons for his assistance with this terminology. 2 RELIGIOUS EDUCATION 3 sutra study, not in secular schools. Groome’s educational theory is also linked to Buddhist pedagogy by Dong (2003). Nevertheless, the order of the three aspects Oh and Park set is not necessarily logical. As Glock and Stark (1965, 20–21) noted, religious knowledge is necessary to create belief. In Buddhism, the process of achieving wisdom includes three steps: learning, reflecting, and practicing. The first step is to study the Dharma and the second is to judge whether it is correct or not; only when we find it is reasonable should we then believe (T. Thich 2011a, 2011b, 142–144). In the time of Shakyamuni Buddha, outsiders only placed their faith in the Three Jewels after hearing his words (see Vappa Sutra in Madhyamagama [S. T. Thich 2019, 95–102]). Therefore, understanding must come before faith. Based on this theory of Buddhism, the process of Buddhist religious education follows this sequence: (1) teaching activities, (2) understanding, (3) faith, and (4) practice. Methodology Study design This study was designed as exploratory sequential mixed method research to explore how Buddhist education provided by three Zen monasteries belonging to the Truc Lam (Bamboo Forest) Zen sect could help teenagers control antisocial behaviors.3 Participants After being informed of the aims of the study, all 140 adolescents aged 12–18 who had been attending every Sunday retreat at the three Zen monasteries for a period of 6 months volunteered to join (mean age ¼ 14.89, SD ¼ 2.17; male ¼ 81 [57.9%] and female ¼ 59 [42.1%]). This group was known as the experimental group, which was surveyed twice using the questionnaire . In the second survey, 11 participants withdrew because they were over 18. At that time, another 11 teenagers who had just reached the age of 12 years agreed to participate in the group. Despite the changes in membership, this was still the experimental group. Hence, the total number of participants was unchanged between the two surveys (mean age ¼ 14.56, SD ¼ 1.95; male ¼ 77 [55%], and female ¼ 63 [45%]). A separate group acted as the control group: it consisted of 81 members who had not attended any retreats offered by the Zen monasteries before agreeing to take part in this study (mean age ¼ 14.74, SD ¼ 1.44; male ¼ 30 [37%] and female ¼ 51 [63%]). This group was only surveyed once, at the time the second survey was done with the experimental group. Participation in the study was approved by the retreat organizers and the participants’ parents, who provided written consent (sought after the teens volunteered). Prior to that, the research proposal had been summited to Tran Nhan Tong Institute, Vietnam 3 Truc Lam Buddhism laid the foundation for social morality under the Tran Dynasty in Vietnam. Its teachings and practices were intended not only for Zen masters but also for all people because its doctrines stated that everyone had the Buddha-nature. 4 L. T. LE National University, for official ethical approval, and the Institute then supervised the study’s progress. Setting Facing a recent rise in antisocial behaviors in adolescents, many Vietnamese parents have tended to send their children to Buddhist pagodas to learn and practice Buddhist principles (Hong 2019; Nguyen 2020). They hope their children will then behave better. Thus, some pagodas have held retreats for teenagers. As stated, three Truc Lam Buddhist Zen monasteries organized retreats in two forms: every Sunday and as a block course in summer to give the teens more options. During the retreats, adolescents took part in a range of activities including Dharma teaching, meditation guidance, and taking lunch mindfully (see the schedule in Appendix A). Measurement Four variables were examined in this article: teaching activities, understanding, faith, and practice. Teaching activities Although the schedule included different activities, this study investigated the Dharma teaching and meditation guidance, because they may have a considerable impact on adolescents. Dharma teaching The monks or nuns taught the teens the doctrines preached by the Buddha and how to apply them to their everyday life. Each session lasted for around 45 min. Meditation guidance Meditation can be practiced in four postures: walking, standing, lying down, and sitting, of which the last one is the easiest. The monks or nuns taught the teens how to sit for meditation. At the retreat, they had around 45 minutes to practice it. They were also encouraged to practice for at least 30 minutes at home every day. At lunchtime, the teens learned how to have lunch mindfully and embrace gratitude to those who had made food for them. During lunch, they also practiced self-reflection to recognize greed, anger, and ignorance arising in their mind and aim to abandon these things. They were taught to use this technique any time during the day or even while sitting for meditation. After lunch, they projected merit and virtues to all sentient beings in general and almsgivers in particular. Teaching activities covered seven items based on responses made by the teens to the following statement: (1) You find it easy to understand the Dharma lessons provided by the monks or nuns, (2) You like their teachings very much, (3) You can apply the doctrines you have learned, (4) You have learned how to meditate, (5) You have learned how to have mindful lunch, (6) You have understood the meaning of the steps in the RELIGIOUS EDUCATION 5 process of having mindful lunch, and (7) You have found mindful lunch helpful. Responses were recorded using a Likert-type scale ranging from 1 (completely disagree) to 5 (completely agree). The scale had good internal consistency (Cronbach’s alpha ¼ 0.781). Understanding The study investigated the teenaged partcipants’ understanding of Buddhist doctrines. They had learned the Life of the Buddha, the Five Precepts, the Law of Cause and Effect, the Four Debts of Gratitude, and the Six Rules of Harmony before the first survey was conducted. Therefore, 20 multiple choice questions about those doctrines were designed to test their understanding (see Appendix B). Ten of them were presented in each of the two surveys. One point was given for each correct answer. The average scores were used in the evaluation. Faith Using Oh and Park’s (1988, 252) definition, belief in the Buddha-nature was probably difficult for the adolescents to understand in this research context, because they were only beginners. The definition provided by Saddhatissa (1970, 56) and Rahula (1974, 8) may be more appropriate, which is faith in the Three Jewels: the Buddha, the Dharma, and the Sangha. The Buddha The Buddha discovered that the causes of suffering were greed, anger, and delusion; if people could get rid of these, they would be happy, and all beings could achieve Buddhahood (Yin and Ho 2002, 29; H. Thich 2011a, 2011b, 32–33). After his awakening, he went all around India to teach people how to live wisely and happily. The Dharma Dharma is what the Buddha taught. Due to the broad and complex nature of the Dharma, which can vary in different contexts, the Buddha’s teaching must be defined for research purposes. This study surveyed the Five Precepts, the Law of Cause and Effect, the Four Debts of Gratitude, and the Six Rules of Harmony, which the adolescents had learned in the retreats. The five precepts The Precepts are no killing, no stealing, no committing improper sex acts, no lying or saying harmful things, and no taking alcohol or intoxicants. The monks or nuns taught the rules to the teens through Buddhist stories and encouraged them to observe as many as possible to achieve happiness in their lives. 6 L. T. LE The law of cause and effect The Law is an axiom that cites the relationship between an action and its corresponding result. Adolescents learned the principle via Buddhist stories, and this was reviewed in different contexts so that the teens were familiar with it. This doctrine is very important because it can cause them to examine their own thoughts, words, and actions. The four debts of gratitude The Debts include gratitude to parents, the Three Jewels, the motherland and society, and all living beings. The doctrine was not only taught in Dharma classes, but also reviewed at the Ullambana Festival held by the Zen monasteries. On this occasion, many Vietnamese people, both Buddhists and non-Buddhists, show filial piety to their parents, with Buddhists also going to pagodas to make offerings to the Triple Gem (Dang and Nguyen 2014; Trinh 2015; Vo and Nguyen 2016). Teenagers could also learn those debts of gratitude through Buddhist songs taught by the Brothers and Sisters (young lay followers who assisted the monks or nuns at the retreat). The six rules of harmony These rules refer to the harmonies of dwelling together, speech, views, discipline and study, shared benefits, and discussion. The monks or nuns not only taught teenagers the content of each rule, but also drew examples from modern life to illustrate it. They encouraged the teens to give examples from their family and school lives. The Sangha The Sangha were originally the Buddha’s disciples, who left home to live and work together in line with the Six Rules of Harmony, teaching living beings on the Buddha’s behalf. In this research context, the Sangha are also contemporary monks and nuns at the Zen monasteries where the adolescents came to join the retreats. The variable of faith in this research context thus consisted of six items: belief in the Buddha, the Five Precepts, the Law of Cause and Effect, the Six Rules of Harmony, the Four Debts of Gratitude, and the Sangha. The response scale for each item ranged from 1 (complete disbelief) to 5 (absolute belief). The reliability values of the scale had alpha coefficients of 0.835 and 0.895 for the first and the second surveys, respectively. According to Bonett and Wright (2015), these values are satisfactory. Practice Religious practice is the most fundamental aspect of Buddhism (Baptist 1991, vi). There are different ways of practicing Buddhism, including chanting the sutras, reciting the Buddha’s name, meditating, practicing mindfulness, and donating (H. Nguyen 2017a). This research examined three aspects: the extent to which the teenagers could apply what they had learned from Buddhist doctrines (1: inapplicable; 5: very applicable); the frequency of teenagers’ seated meditation at home (1: never; 5: very often); and the frequency of teenagers’ self-reflection (1: never; 5: very often). The first was known as RELIGIOUS EDUCATION 7 doctrine practice. Meditation practice is a new variable computed from the mean of the second and third questions. Moral behavior and “antisocial behavior” The teenagers self-reported their frequency of committing antisocial behaviors in the past year. This is understood to be behavior that violates social and traditional norms. The variable included 11 items selected from findings on antisocial behavior in adolescents published by Vietnamese scholars (H. Phan 2016; V. Dinh 2017; T. Nguyen 2017b; T. Pham 2017, 2018; K. Do 2019): lying to others because of negative motivations; cheating on examinations/tests; playing truant; fighting with others; using foul language/swearing; stealing the belongings of other people (regardless of their value); littering in public places; quarreling with others; hurting grandparent/parent by words or acts; using addictive substances; and not saying thanks after receiving gifts or help from others. The items were rated on a seven-point scale (1 is none, 2 is 1–2 times, 3 is 3–4 times, 4 is 5–6 times, 5 is 7–8 times, 6 is 9–10 times, and seven is more than 10 times) developed by Ma (2015). The reliability value of the scale had an alpha coefficient of 0.789. Procedure First, we investigated the retreat program and interviewed four teenagers and four teachers, using semi-structured questions. We also observed how the program was run. This helped to identify what research issues needed focusing on and informed the construction of the questionnaire. The questionnaire was then pre-tested by surveying a group of 34 teenagers who joined every Sunday retreat at one of the three Zen monasteries. Following analysis of the pre-test, two other groups at the two other monasteries also completed it. The survey focused mainly on examining teaching activities, the teens’ understanding of Buddhism, and their faith. To examine the reasons why they had faith in Buddhism and how they changed their behavior as a consequence of Buddhist education, we conducted 12 in-depth interviews with teenagers attending every Sunday retreat. There were six males and six females, who used to have behavioral problems including bullying, fighting, quarreling, and failing to apply themselves at school. Each interview lasted 30–45 min. Six months later, we conducted the second survey using the second questionnaire. It again consisted of questions to investigate the teens’ understanding and their faith. It also included items to evaluate the frequency of committing antisocial behavior. The control group completed this questionnaire as well. All questionnaires were anonymous, distributed directly to the adolescents in groups on the days they came to the Zen monasteries to attend the retreats. The control group completed the questionnaire on the first day of the retreat when they had not learned anything. Data analysis The resulting dataset was analyzed using Student’s t-test and Spearman’s correlation with SPSS version 20 software (SPSS Inc., Chicago, IL). 8 L. T. LE Figure 1. Correlation between the aspects of the Buddhist educational process. Note. p < .05 (2tailed) and p < .01 (2-tailed). Results The findings from the first-time survey revealed positive associations between the aspects of the Buddhist educational process (Figure 1). The variable of teaching activities positively correlated with the teens’ understanding (rs [138] ¼ 0.19, p < .05) and it also had a positive association with their faith (rs [138] ¼ 0.55, p < .01). In addition, their understanding positively related to their faith (rs [138] ¼ 0.21, p < .01). The data analysis from the second investigation continued to reflect a positive connection between the components of Buddhist education (Figure 2). Understanding and faith had a positive relationship with each other (rs [138] ¼ 0.28, p < .01). Faith was positively associated with the teenagers’ doctrine practices (rs [127] ¼ 0.24, p < .01), but it did not correlate with meditation practice (p ¼ .1). The most remarkable finding was that there were significant relationships between the components of the Buddhist educational process and the occurrence of antisocial behavior (Figure 2). Understanding negatively correlated with antisocial acts (rs [138] ¼ 0.21, p < .01). The teens who had better religious understanding committed antisocial behavior less often. Importantly, doctrine practices also had a negative connection with antisocial behaviors (rs [127] ¼ 0.18, p < .05). The more teenagers practiced Buddhist doctrines, the less often they committed antisocial acts. Noticeably, faith did not have any association with negative actions (p ¼ .95). The data collected from the interviews also indicated that Buddhist education could encourage adolescents to develop their moral behavior by improving their understanding. Interestingly, their faith was also fostered by their growing knowledge and fruitful practice. Previously [the time before she came to the retreats], I did not know anything about Buddhism, and so I did not have faith in the Law of Cause and Effect. I did not care about everyone surrounding me and how they felt. I did not also pay attention to my study. I did not help my grandparents [she lived with them]. I watched TV or hung out with my friends all day. I usually played truant to stay home for sleeping or going out with my friends. When I learned the teachings from the Buddha, I am more thoughtful. I know how to take care of my grandparents and help them do the housework such as cooking, cleaning, and washing up. In particular, I have been keener on my study. My study outcome is much better now. They are the Dharma lessons on the Law of Cause and Effect and the Life of the Buddha that have made me change. The Buddha got rid of his wealthy life and overcame a lot of difficulties to reach height. Why can I not do it? Therefore, I have strong faith in the Buddha and the Law of Cause and Effect now. (15-year-old female) I thought about the Law of Cause and Effect and recognized that it worked very well with me. When someone hurts me, I think about it, and then my anger disappears immediately. RELIGIOUS EDUCATION 9 Figure 2. Correlation between the aspects of the Buddhist educational process and the teens’ antisocial behavior. Note. p < .05 (2-tailed) and p < .01 (2-tailed). So I believe it. The Buddha? I do not care if he was a genuine person, but the most important thing is that he had a kindly manner I can learn. He sat meditating under the Bodhi Tree for 49 days and nights. He worked very hard; meanwhile, I spent my time sleeping much more than studying. Learning from Him, I have studied harder and harder, and I am in the first place in math, physics, and chemistry in my class. And so I have great faith in Him. (17-year-old male) It was faith that could keep the teens following Buddhism. Monks or nuns also played a vital role in reinforcing it. Firstly, I did not often attend the retreats because I had no faith in the retreat program. Then I stayed home for the time, and one day I felt that I had missed something and then I joined again. After receiving the Dharma lessons from the monks/nuns and being informed of how the retreats work, I had great faith. (18-year-old female) The qualitative data also suggested that teenagers could control their antisocial acts if they practiced meditation at home. A 17-year-old male sat in meditation at home for approximately a half hour each day; as a result, he could bottle his negative emotions up, which might otherwise have led to aggressive behavior, as found by Fazel et al. (2015); Mestre, Malonda, and Samper-Garcıa (2017); and Heinze et al. (2017), who found significant correlations between psychological problems, such as anxiety, depression, and stress, and violence in adolescents aged 15–18. My favorite time is meditation time. At that time, I do self-reflection to change myself. Sometimes I remember being bullied by other students when I was in my lower secondary school, and the feeling of deep hatred for them runs high. Meditation sitting helps me let it go. [ … ] I sit in meditation for 30 minutes every day. A 14-year-old male experienced the fruitfulness of self-reflection in his daily job but not in seated meditation. Thanks to that technique, he could control his bad temper. When my friends tease me, I am angry, and I recognize how it is going up in my mind. Before that [before the time he came to the retreats], I did not see it because it "swallowed" me. Thanks to self-reflection, I recognize the "fire" in my mind, then it went out immediately, and my mind came down. To explore how Buddhist education could improve behavior in teenagers, the performance of the two groups was compared with each other. The results showed that the 10 L. T. LE Table 1. Differences in Performance Between the Two Groups Experimental group (N ¼ 140) Control group (N ¼ 81) Understanding M (SD) p 5.5 (1.62) .000 4.1 (1.81) Faith M (SD) 4.34 (.71) 3.94 (.66) p .000 Antisocial behavior M (SD) p 2.12 (.89) .02 2.42 (.95) Note. M: mean; SD: standard deviation p < .05, two-tailed. experimental group had better performance (Table 1). They committed antisocial behavior less often (M ¼ 2.12, SD ¼ 0.89 versus M ¼ 2.42, SD ¼ 0.95; p ¼ .02). The outcome also partly reflected the reasons why they had performed more adequately, because they had greater understanding (M ¼ 5.5, SD ¼ 1.62 versus M ¼ 4.1, SD ¼ 1.81; p ¼ .000) and greater faith (M ¼ 4.34, SD ¼ 0.71 versus M ¼ 3.94, SD ¼ 0.66; p ¼ .000). Discussion The findings illustrated that Buddhist education could control self-reported negative behavior in adolescents using the following sequence: Teaching activities enhanced their Buddhist understanding, increasing their faith, which promoted their practice. It was the practice that helped them control their negative actions, which corroborates Baptist’s (1991, vii) argument for the importance of application in Buddhism. It also supports the claim made by Sivasai (2014, 75) that people can acquire the knowledge, skills, attitudes, and values that are vital in planning for a sustainable future. Buddhist education can be defined as a process in which teachings can change learners for the better by enhancing their religiosity, which consists of these dimensions: understanding of religion, faith, and practice. Faith, as defined in this research, was not as essential in developing moral behavior as Oh and Park (1988, 252) had claimed. However, the interviews showed that it was necessary for the teens because if the teens do not have faith, they may leave Buddhism. This is in good agreement with what the Buddha preached in the Avatamsaka Sutra (Cleary 1993, 331): “Faith is the basis of the Path, the mother of virtues. Nourishing and growing all good ways.” The results also indicated the significant role of understanding developed by teaching activities. Understanding both fostered the faith of the teens and helped them control their antisocial behavior. The finding supports Oh and Park’s (1988, 253) recommendation that teachers have to be responsible. If they had not performed well, their students would have not changed for the better. Moreover, the qualitative data showed that meditation practice worked well with adolescents, allowing them to recognize their negative emotions, which could otherwise lead to negative behaviors (Fazel et al. 2015; Mestre, Malonda, and Samper-Garcıa 2017; Heinze et al. 2017). The finding is in line with what the Buddha taught in the Dharmapada (Buddharakkhita 1985, 23): Mind precedes all mental states. Mind is their chief; they are all mind-wrought. If with an impure mind a person speaks or acts, suffering follows him like the wheel that follows the foot of the ox. Basically, the Buddhist education offered by the Zen monasteries achieved their primary goal, which was to help the teens control their behavior. Comparing the RELIGIOUS EDUCATION 11 performance of two groups showed that the experimental group committed negative acts less often than the control group thanks to Buddhist education. Committing such acts less often meant that teenagers could gradually abandon their greed, hatred, and delusion, bringing them, their family, and their community happiness. That is very similar to what the Buddha explored. As a result, the Truc Lam Zen monasteries should extend it. There may be an argument about unfair comparison because of the unbalanced proportions of males in the two groups. In this study, the two groups of adolescents had nearly the same mean age (14.56 versus 14.74), but the proportion of males in the control group was much lower (37 versus 55%). As discovered by Trillo and Redondo (2013), Mobarake (2015), and Santos et al. (2019), males tend to engage in antisocial behavior more often than females. The findings of this study significantly differ from these previous studies. There were no differences in the incidence of antisocial behavior between the two genders (M ¼ 2.24, SD ¼ 0.90 versus M ¼ 2.00, SD ¼ 0.86; p ¼ .07). That is consistent with the spirit of the Truc Lam Zen sect: all people are equal, having the Buddha-nature (T. Thich 2013, 204). If they all practice, all of them can live morally. The quantitative data analyzed demonstrated no differences in doctrine practice and meditation practice between the two genders (p values were .80 and .06, respectively). The findings also support what L. T. Nguyen (2019), H. D. Le (2019), H. T. Le (2019), and Tran and Nguyen (2019) proposed with regard to teaching Buddhist doctrines to the young. Buddhist doctrines such as the Five Precepts, the Law of Cause and Effect, the Six Rules of Harmony, and the Four Debts of Gratitude may not be too difficult for teens to understand. According to H. Thich (2011a, 2011b), these doctrines can establish a foundation for beginners. The scale for measuring the teens’ faith worked very well. It was reliable (Cronbach’s alpha ¼ 0.895). Furthermore, it embraced all the key components of Buddhism (the Three Jewels). It is also very flexible because the items referring to faith in the Dharma can be replaced by various other Buddhist doctrines, depending on who the research subjects are. The mixed methods employed benefited the study considerably. Quantitative measures could reveal the extent to which teenagers understand, believe, and practice Buddhism, but could not provide extensive evidence about why they had faith in Buddhism. The qualitative approaches helped to explore inner elements; for instance, the experiences the teens gained from meditation practice. Inevitably, there were some limitations. First, the questionnaire used for the control group did not investigate how the participants practiced Buddhism, and thus missed a chance to compare the Buddhist practices of the two groups. That is partly because the teens in the control group were thought not to have previously obtained Buddhist education provided by the Zen monasteries, and partly because they may have had many different ways of practicing, making them difficult to compare. It is also because the timetable set for the teens in the control group at the retreats was so busy that we could not arrange in-depth interviews with them, so we were unable to explore how they were practicing Buddhism. In terms of the moral behavior measurement scale constructed by Ma (2015), the timeline was quite long ( a year), which could have caused difficulty for the 12 L. T. LE participants in recalling what they had done. Therefore, it should be shortened to six months. Finally, data collected from self-reports may reduce reliability. Hence, further studies need to include observations or/and surveys involving relatives and teachers. Acknowledgments We would like to thank the retreat organizers and the monks and nuns at the Truc Lam Zen monasteries of Vien Chieu, Chinh Phap, and Ham Rong for supporting this research. We also thank the teenagers for their participation. Disclosure statement There is no potential conflict of interest.
